ASCO 8320G172 Three Way Quick Exhaust Solenoid Valve

ASCO 8320G172 is a three‑way, two‑position quick‑exhaust solenoid valve with a 1/4 in NPT/pipe connection, designed for fast venting in compact pneumatic circuits. The brass‑bodied valve is configured for 120 V AC operation (60 Hz) in the common variant, with 110 V AC or 120 V AC options often listed by retailers for this model. It features a 1/16 in orifice and a Cv of 0.09, enabling precise flow control within a maximum differential pressure of up to 125 psi for air or inert gas. This is a quick‑exhaust type valve, typically configured without a junction box on the coil, suitable for integration in HVACR and industrial automation environments where compact, reliable three‑way control is required to direct supply and exhaust ports or vent pilot lines.
